METHOD OF PRODUCING HYDROCARBONATE OF ALKALI METAL Russian patent published in 2009 - IPC C01D7/40 C01D7/10 

Abstract RU 2347748 C2

FIELD: chemistry.

SUBSTANCE: present invention can be used in production of hydrocarbonate of an alkali metal. The method of producing hydrocarbonate of an alkali metal involves reaction of an aqueous solution, containing alkali metal ions, with carbon dioxide in a crystalliser. Part of the suspension, containing the given crystals in the given aqueous solution, is removed from the crystalliser and returned into the crystalliser, after dissolving part of crystals when establishing pressure over the suspension, removed from the crystalliser, lower then pressure in the crystalliser.

EFFECT: simplification of industrial production of hydrocarbonate of alkali metal with coarse particles.
